Be it known that l[, HAROLD 0'. STRONG, a

citizen of the United States; residing at- Clearwater, in the' count of Los Angeles and State of California, ave invented new and useful Improvements in Brakes for Auto Vehicles, of which the following is a specification. I

lit is the object of this invention to provide a brake particularly adapted to be employed in connection with the drive wheel of a motor vehicle.

The improved brake structure provides a device wh1ch will be positive and eihcient in its action and which may be readily operated. a

The invention will be readily understood from the following description of the accompanying drawings, in Which-- Figure 1 is a longitudinal section through a wheel and the improved brake.

Fig. 2 is a transverse section on the line 2--2 of "Fig. 1, partly broken away.

lln the drawings 1- have shown a usual automobile wheel 1 mounted upon a usual axle housing 2 with an antifrictional bear- .in 3 interposed betweenthe wheel and the" ax e housing, and a nut t threaded upon the end of theaxle housing for retaining the wheel in position. A usual drive axle 5 rotates in the axle housing and projectsbe yond the same so as to be connected to a"- drive connection fixed uponwheel 1 in order to form a drivin meansfor the wheel.

The improved rake includes a casing secured to the wheel 1 so as-to surround the axle housing!2.- This casing includes-a peripheral portion 9 abutting at one edge against wheel land having the side portion 10extending inwardly from the other edge of the same to a point spaced an ap 'reci able distance from axle housing 2 as s own at 11. The casing is retained in positionby means of' bolts 13 received through wheel 1 with shoulders 1 1 upon said bolts abutting against one side of the wheel, and nuts 15 threaded on to the ends of the bolt at the other side of the wheel. The bolts extend throu h the space within the casin and project t rough the .end portion 10, 0' said casing with nuts 16 threaded onto the projectingzends oi the bolts.

rictional'rings 18 of suitable material surroundaxlehousing 2 in spaced relation therefrom within the casing carried by wheel 1, said frictional rings being slidably mounted upon bolts 13 for axial movement toward and away from one another.

A sleeve 20 is received upon axle houswheel 1 adjacent the surface of the wheel,

and in order to axially shift sleeve 20, the

end of the same which projects beyond the casing secured to wheel 1, is preferably grooved as shown at 23 so that a usual yoke 24l may engage the sleeve at said groove in order to axially shift the sleeve through any suitable operating connection. Pins 25 extend axially from flange 22 radi-v ally beyond sleeve'20 so as to project beyond the brake casing at the space between the rearwall' 10 of said casing and sleeve 20. A plurality of friction rings are mounted upon pins 25 and are disposed within the brake casing between adjacent ones of the friction rings 18. 'The friction rings 26 are free for sliding movement alongthe pins 25. By the construction as thus described it will be seen that when yoke 24: is actuated so as to shift sleeve 20. toward wheel 1,' the sides offriction rings 18 and 26 will be disengaged so that no braking action is produced, but when sleeve 20 is axially shifted in theopposite direction throu b its operating connection, the friction rings 18 and 26' are drawn toward end wall 10 of the brake casing and are clamped against one another and against said wall by the flange 22 of the axiall movable sleeve. sequence a bra ing action is produced be tween the rotating friction rings 18 and the -non-rotating friction rings 26, the degree of said braking action being varied, asfound desirable, by varyin the same time is extremely simple in-constructionand conveniently manipulated.

, Various ohangesmay' be made without departing from the spirit of the invention.

What is claimed is: v

A brake comprising the combination with an axle housing, an axle in the axle housing and a wheel suitably mounted and connected to the axle, of bolts fixed in the Wheel' and extending inwardly, a casing end of the sleeve next to the Wheel, pins mounted against the inner face of the wheel fixed in the flange arallel with the bolts around the bolts and having a side portion and'inside of the frictional rings, second extending inwardly, said bolts extending friction rings slidingly mounted upon the 5 through said side portion, nuts upon the pins"between the first friction rings, and 15 bolts tohold the casing in place, frictional means for sliding the sleeve to tighten or rings loosely surrounding the housing and loosen the friction rings upon each other. slidingly mounted upon the bolts Within the In testimony whereof I have signed my casing, a sleeve slidingly' splined on the name to this specification.

10 axle housing, a flange projecting from the HAROLD C. STRONG.
